CHURN.

Specification of Letters Patent.

Patented A t. 4-. 1916.

Application filed May 13, 1913. Serial-No. 767.359.

To all whom it may concern:

that I ALonzo A. Warmth; United States; and a-resident Be it known a citizen of the of New Britain, in thecounty of Hartford and State of Connecticut, have invented certain new and useful Improvements in Chums, of which the, fnliowing is a specie cation.

The object of this invention is to produce a device of the character described having features of novelty and advantage.

In the embodiment of the invention illustrated in the drawings Figure l'is a side 'view partly in-section. Fig. 2 is a' top View thereof.

Referring to the drawings, ar'denotes a base preferably of metal, having underneath it a screw clamp 12, by-means of which it may be attached to the edge of the table to hold the churn securely while it is in use; 0 is the jar supported by the base and within which the churning action takes-place. It

i has smooth, uninterruptedside and bottom gear 9,

.ternal gear by walls.

d is the cover fitting onto the top of the handle Z, and the intermediate gear 3' is mounted on a stud secured to thehandle Z. is in'theform of a This part of the handle plate which overlies the-meshing point of the gears to a greater or less extent as may be desired to avoid accidents. A washer h. securedtothe upper end of the shaft above.

its bearing holds the shaft and its pinion on the handle so that the handle with the bearing, shaft, and the two gears, can be removed as a unit. The shaft extends through the cover and has secured to its lower end the plate f which is fastened by a thumb screw f. Byth'e operation of this single fastening means the operative parts of the churn mechanism may be assembled ready to be positioned in the jar.

Pivoted in lugs 12 at opposite sides of the from the bottom of the jar. In the "through the cover,

base are the tie rods 1', 1', which are adapted to enter notches s, s, inthe cover. and are provided with thumb .n uts" t, r, 'ov means of which the cover isel-amped Onto the jar, and

the jar onto the base, securely tying the parts of the complete structure together.

I have already made mention of the fact that the interior walls of the jar are quite Smooth. making it possible to thoroughly cleanse the jar after use. The churning mechanism is all carried by the co er and may be removed from the jar as an assembled unit, and then by unfastening a single thumb screw it can be dis-assembled for thorough cleansing of its parts. The retarder prevents the whirling of the cream with the blade, and the apertured marginal edges of the blade in conjunction with the retarder produce the kind of agitation necessary in a successful and quick-acting device ofthis character. The shape of the blade is such that the cream is kept moving in a most effective manner.- 'As it moves laterally onthe center of the blade under the centrifugal'action, itis caughtby the angularly disposed edges and its direction and rate of motion, abruptly changed.

Another feature, worthy of note is that the operative mechanism is all located in a horizontal plane and is comprised of few parts and simple construction, and the operating handle moves in a horizontal plane. The interposed gear is guarded at its meshing'point with the pinion and-internal gear by the handle plate, inorder that the fingers of the operator may not'be caught in the gears. I p

The complete structure is extremely efiicient, and yetsimple in its construction and assembling and it is particularly adapted for manufacture, in'smaller sizes for home use and to handlejsmall quantities of cream.

.I claim as .my invention:- 1. In adeviceof the character described,

a jar. a cover therefor, a shaft extending a blade mounted on the shaft, an operating handle located above the cover a bearing for said shaft mounted on said handle,-.and shaft operated by said handle.

2. In a device of the character described.

a jar, a cover therefor, a shaftextending through the cover, a blade mounted on the shaft, an internal gear formed surface of the cover, anopera in'the upper ting handle gear connections for said above the cover, a bearing for said shaft shaftan intermediate gear connecting said "internal gearand pinion, and a support on said handle for said intermediate gear.

3. In a device of the character described, a jar, a cover therefor, a handle above the cover, a bearing on the handle, a shaft supported in said bearing and extending through the cover, alinedgears on the cover and shaft, an intermediate connecting gear carried by the handle, and a blade removably secured to the shaft belovv said cover.

l. In a device of the character described, a jar, a cover therefor, a shaft extending through said cover and axially .arranged with respect to said jar, an operating handle above the cover, a bearing secured thereto and in which said shaft is supported, a blade removably secured to the shaft below the cover, and gear connections for said shaft actuated by said handle.

iner? 5.111 a device of'the character described, a jar, a cover therefor, an internal gear formed in the upper surface of the cover, an operating handle enlarged at its inner end, a bearing mounted at the inner end of the handle, a shaft supported in said hearing, a pinion secured to said shaft, said cover being centrally apertured to receive end ofsaid shaft at a point below said cover.
